Do I have to change all 4 tires or just the front ones if I want to raise the front end by an inch. Thanks, Bill

All tires should be the same size. If you stagger the tire sizes it will hinder the anti-lock brake and traction control operation,(if equipped). When you go from 14 to15 inch wheels the actual diameter of the tires is supposed to remain the same, otherwise you are modifying all the drive ratios for the vehicle. What I am saying if you have 195 60HR 14 tires and switch to 15 inch wheels the tire size should be 195 55HR 15. The change from a 60 series aspect ratio to a 55 series keeps the tire diameter and also the circumference the same. If you incorrectly change these ratios, you will experience poor handling and reduced safety when driving. I recommend consulting a tire retailer for their recommendations, there are some websites, (like for Tire Rack) that match the correct applications for your vehicle when stepping up the wheel diameter. Good luck.
